This page (translated from French) talks a bit more about the game and the underlying geometry: https://translate.google.com/translate?sl=fr&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fwww.madore.org%2F~david%2Fweblog%2Fd.2015-07-15.2307.html%23d.2015-07-15.2307&edit-text=&act=url …

Last tweet on this. In English the game is called "Spot It!", and here's an accessible deep dive into the math: https://plus.google.com/107909926350520444591/posts/amAe7JaHpdt …

Another nice thing about Spot It! is the points of the projective geometry can be equivalence classes with distinct elements on each line,
-
and the difficulty of the game scales with how expensive it is for humans to compute the equivalence relation.

@avibryant versions with words in place of some pictures are interesting. Sacrifices proj. geom. symmetry, but more cognitively challenging -
@jcreed why does it ruin the symmetry to use words? -
@avibryant not 'ruined', maybe --- bit you could get 2 pics, 2 words, or 1 pic/1 word, & seems less canonical wrt finite proj. plane math -
@avibryant but maybe I'm wrong and there's some 'nice' choice of how to choose pic vs. word on all cards at once? would be nice if so -
@jcreed oh, you mean that sometimes you'd have a picture of a horse on one card and "horse" on the other? -
@jcreed yes, that would be more interesting (especially for kids learning to read) and does destroy the symmetry a bit. -
@avibryant yup that's the version I saw. Seems like a fun way to teach reading though! -
@jcreed you could regain some symmetry/elegance if you had N different representations, ie if you had an image + words in 7 languages. - 2 more replies
